The vacuum level is determined by the pressure differential between the evacuated volume and the surrounding atmosphere. Several units of measure can be used. Most refer to the height of a column of mercury â usually inches of mercury (in.-Hg) or millimeters of mercury (mm-Hg).
Contraction of the diaphragm causes it to flatten, lowering its dome. This increases volume in the thoracic cavity and creates a vacuum. This vacuum inflates the lungs by drawing air into the body.Boyle's Law-If the size of a closed container is increased, the pressure of the gas inside the closed container decreases.his increases volume in the thoracic cavity and creates a vacuum.
